A leaked roadmap earlier this year claimed that Office for iOS and Android wouldn't be available until 2014, but one of those is already seeing the light of day. Microsoft officially launched their Office Mobile application today, and it is now available for iOS users.

Rumors had stated that Microsoft would be using Office 365 to regulate their mobile app, and that is exactly the case. Only customers with an Office 365 subscription are able to use any functionality in the Office for iOS app, and it is available as an in-app purchase for $99.99.

After logging in with their Office 365 account, users will have access to the full Office suite, including Word, Powerpoint and Excel. Sadly, only Word and Excel documents can be created through the app, but editing capabilities do include Powerpoint presentations. In addition, the application supports the use of animations, SmartArt and SkyDrive, which allows access to files across systems.

The app is so far unavailable in an iPad edition, and there is also no mention of Android or even Windows Phone versions of the software. In any case, it can currently be acquired for free through iTunes, and includes support for English, Japanese, Italian, German and many other languages.
